Coreopsis plant named ‘Garnet’

ABSTRACT

A new and distinct  Coreopsis  plant named ‘Garnet’ characterized by daisy-type flowers that grow to 4.5 cm in diameter, flowers that are deep rose with a darker center, grass green foliage on short stems, flowering for the whole summer, a dense, compact, mounding habit, and excellent vigor.

Botanical denomination: Coreopsis spp.

Variety designation: ‘Garnet’.

Parentage: (Coreopsis ‘Heaven's Gate’×unknown).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Coreopsis and given the cultivar name ‘Garnet’. Coreopsis is in the family Asteraceae. This new cultivar originated from an open pollinated cross of Coreopsis ‘Heaven's Gate’ (U.S. Plant Pat. No. 16,016) as the seed parent and an unknown proprietary Coreopsis as the pollen parent.

Compared to the seed parent, Coreopsis ‘Heaven's Gate’ (U.S. Plant Pat. No. 16,016), the new cultivar has flowers that are deep rose with a dark center rather than pink with a dark center and the habit is much smaller and tighter.

Compared to Coreopsis ‘Limerock Ruby’ (U.S. Plant Pat. No. 15,455), the new variety has flowers that are deep rose with a dark center rather that ruby red. The habit is shorter and more compact.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of the new variety. These characteristics in combination distinguish Coreopsis ‘Garnet’ as a new and distinct cultivar:

-   -   1. daisy-type flowers that grow to 4.5 cm in diameter,     -   2. flowers that are deep rose with a darker center,     -   3. grass green foliage on short stems,     -   4. flowering for the whole summer,     -   5. a dense, compact, mounding habit, and     -   6. excellent vigor.

This new cultivar has been reproduced only by asexual propagation (cuttings and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by cuttings and tissue culture using standard micropropagation techniques with terminal and lateral shoots, as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.
